After copying & pasting the object into Word, I get one with dimensions of 18.89cm*13.28cm (w*h). Simply drag the width handle to increase the overall width to 19.2cm or more. Alternatively, you could use Paste Special with the 'Enhanced Metafile' option. The advantage of the latter is that you can then re-scale the entire object without worrying about text-wrapping issues that a plain paste has to deal with.
